8.3.1.1 Gain Error and Drift

Gain error in INA351 is limited by the mismatch of the integrated precision resistors and is specified based on characterization results. Gain error of maximum 0.1% can be expected for all gains of 10, 20, 30 and 50. Gain drift in INA351 is limited by the slight mismatch of the temperature coefficient of the integrated resistors. Since these integrated resistors are precision matched with low temperature coefficient resistors to begin with, the overall gain drift is much better in comparison to discrete implementation of the instrumentation amplifiers built using external resistors.
